Student Workbook Physics Labs with Computers, Vol. 1012-07000A Tutorial Activities: Photogate/Pulley System• Click the ‘Timing Sequence Choices’ menu button again and select ‘Unblocked’. Result:The ‘Unblocked Photogate’ icon appears next to the ‘Blocked Photogate’ icon in theTiming Sequence area. Click ‘Done’ to return to the setup window.Set up the sensor in the ScienceWorkshop software• In ScienceWorkshop, click-and-drag the ‘digital sensor plug’ icon to the Channel 1 icon inthe Experiment Setup window, select ‘Photogate & Solid Object’ from the list of sensorsand click ‘OK’. Result: The sensor’s parameter window opens and shows the default valuefor the ‘Object Length’ as 10 cm (0.100 m). Click ‘OK’ to return to the Experiment Setupwindow. Result: The sensor’s icon appears below Channel 1 of the interface.Set up a display• In DataStudio, double click ‘Digits’ icon from the Displays list. Result: The Digits displayautomatically shows ‘Time in Gate’. Repeat the process to create a ‘Table’ display.• In ScienceWorkshop, click-and-drag the ‘Digits’ display icon to the sensor’s icon in theExperiment Setup window. Select ‘Time in Gate’ from the list and click ‘Display’. Repeatthe process to create a ‘Table’ display.Start recording data• In DataStudio, click the ‘Start’ button ( ). In ScienceWorkshop, click the ‘REC’button ( ).• Block and then unblock the Photogate’s beam several times. Watch the results in the Digitsand Table displays. Find out how quickly you can move the card through the beam.Stop recording data• Click ‘Stop’ to end data recording.©1999 PASCO scientific A - 35
